Cowboys already looking for OL reinforcements

The Dallas Cowboys are already looking for reinforcements on the offensive line.

With four interior linemen hurt and not available for practice less than a week into training camp, the Cowboys worked out three of their former lineman Friday.

Montrae Holland, Derrick Dockery and Daniel Loper all were in Dallas' organization last season. Holland and Dockery started games. It wasn't clear if the Cowboys would sign any or all of them.

Coach Jason Garrett says with the rash of injuries, the Cowboys need to get some guys in camp who can play.

Guard Nate Livings sustained a hamstring injury in camp, and center Bill Nagy has a high left ankle sprain. Guard Mackenzy Bernadeau and center-guard Kevin Kowalski started camp on the physically unable to perform list.
